My front diff normally feels a bit stiffer, but I run 50k front vs 20k rear. I've found that the front CVDs/dog bones can bind at full extension. Sometimes tightening the droop screws a couple turns will bring the arms up enough to reduce binding. In addition, you can add a shim or washer to the A-arm/pillow ball area to create more lateral space and relieve binding should that be the issue. Hope this helps.So if I turn the rear tires by hand in opposite directions they turn smooth when I do the same on the front tires they kinda drag any ideas on what would cause this?
